How to find VPN tunnel BW

[asoka]

Hi,

My router is 2851 and running :c2800nm-adventerprisek9-mz.124-24.T2.bin

And I have 13 differenet IPSec vpn tunnels to other locations

How can I find the each VPN tunnel bandwidth

I explore teh NBAR method, aand its dont recognise IPSEC traffic

And,

sh crypto engine accelerator statistic

command give yo last 5 minutes bits/sec in and out capacitry but it is the total.

I thought I can go to other end, which is 1760 routers and they dont give you 5 mts tarffic in and out info like 2851

Hello Asoka,

I would use

ip accounting output-packets

on physical interface of HQ router

you should be able with

sh ip accounting

to see the flows of IPSec you know the endpoints IP addresses

or an ACL with log option with one line with log option for each IPSec tunnel

Hope to help
